Using ammonium to correct pH drift

January 17, 2017

This is not actually someone’s question, but it is a problem met by many hydroponic growers both hobby and commercial. Unfortunately, it is rarely mentioned in most hydroponic books and forums.

For growers using media based systems, pH drift is a significant change in pH between the dripper solution and the run-off solution. It is usually a rise in pH. For a water–based system without pH control, it is a change in pH with time, For a water-based system with pH control, while the pH remains steady, it results in the addition of an excess amount of acid. In turn this results in the nutrients in the recirculating solution getting out of balance.

So, how and why can ammonium be used to correct thisdrift?
